Chronoamperometric deposition of PVP encapsulated Ag2S films (inset: LSV curve)
HRTEM images of PVP encapsulated Ag2S thin films: (a) low magnification image showing the complete core-shell, (b) two overlapped core-shell structures, (c) interface of crystalline Ag2S and amorphous PVP, (d) lattice fringes showing the “d” value.
(a) FESEM image showing nearly spherical particles, (b) particle size distribution curve, (c) HRXRD pattern, and (d) UV-vis-NIR absorption spectrum (inset: magnified spectrum between 950 and 1050 nm) of the electrodeposited Ag2S-PVP thin films.
(a) NIR-PL spectrum of the PVP encapsulated Ag2S film showing a broad emission peak at around 1040 nm and (b) FTIR spectrum of the deposited material.
(a) Schematic for frequency switching measurement, (b) photo-induced frequency switching characteristics of the film due to excitonic transition, (c) energy diagram for bare Ag2S NPs, and (d) energy diagram for PVP encapsulated Ag2S NPs.
